A smiling face composed of a yellow background circle, two black eyes, and a curved mouth is displayed against a blank page. The example demonstrates a component-based React approach to SVG rendering, built with React 17 and D3 v6. Each facial feature is defined as a separate React component, with the mouth using the D3 `arc` generator to create its path. The face is centered within a 960x500 SVG canvas using a translation transform applied to a group element.
